C. Marsh for Thomas Henry Huxley after Marsh had shown his recently collected Western fossils to Huxley on his only visit to the United States.

Not a single well-documented fossil had been found from any time before the Cambrian explosion, and the earliest evidence of multicellular animals coincided with the earliest evidence of any life at all! From time to time, claims had been advanced—more than once by Walcott himself— for Precambrian animals, but none had withstood later scrutiny.
